Few employees have left as visible a mark on National Park Service (NPS) exhibits as John A. Segeren. His work has been enjoyed by generations of park visitors who never knew his name but appreciated his intricate wood carvings and playful animal figures displayed in parks throughout the system. A master woodcarver described by former President Lyndon B. Johnson as "a legacy to this country," Segeren carved out his own place in NPS history.
